Suarez was speaking with Sports Illustrated.
"Secondly, you react in a fraction of a second. Something that may not seem like a big thing suddenly is and you aren't conscious of your reaction or the repercussions."
He insisted: "My conscience is clear. Firstly, I am not a racist. There are a lot of people who could testify to that.
"Secondly, there are conversations that happen on the field, where a lot gets said.
"I am at peace. Of all the video that was available, there was not one piece of evidence to prove I had said something racist."
But Suarez added: "I've had some elements on the field that weren't very good for the game. They weren't really me. Off the field I am very shy. But I realised I had to adjust my attitude on the field.
"I want to continue to play well - without the bad attitude."
